Does ctime return the Gregorian calendar date?

Question

Does the standard C ctime function return the Gregorian calendar date? In particular, I want to verify that it will account for leap years and thus display Feb 29 for the respective dates.

Answer 1

For times in the future and in the recent past, yes. For times before the Gregorian calendar reform... I don’t know, but those times are only relevant on systems with 64 bit time_t.
